Critical 9.1

A critical-severity server-side request forgery in squidex from Squidex. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.5% (higher than 42% of all known vulnerabilities).
Official description
Squidex is an open source headless content management system and content management hub. Versions of the application up to and including 7.21.0 allow users to define "Webhooks" as actions within the Rules engine. The url parameter in the webhook configuration does not appear to validate or restrict destination IP addresses. It accepts local addresses such as 127.0.0.1 or localhost. When a rule is triggered (Either manual trigger by manually calling the trigger endpoint or by a content update or any other triggers), the backend server executes an HTTP request to the user-supplied URL. Crucially, the server logs the full HTTP response in the rule execution log (lastDump field), which is accessible via the API. Which turns a "Blind" SSRF into a "Full Read" SSRF. As of time of publication, no patched versions are available.
